CCCC MS 73, of the second quarter of the fifteenth century, is a copy of the commentaries of Nicholas de Gorran OP (1232-c.1295) on Matthew, Mark, the Catholic Epistles and the Apocalypse. The opening flyleaf of this manuscript is from an antiphoner and includes some music on a four-line stave. James noted a similarity in appearance between this manuscript and CCCC MS 1.
